WARNING: This page is about a different car, the 2019 RAM 3500 HD and 2019 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
This Electronic Control Unit (ECU) compares the vehicle configuration stored in memory with the configuration information transmitted on the Controller Area Network (CAN) by other ECUs. If the vehicle configuration stored in memory does not match the information transmitted on the CAN, this DTC will set.
If the vehicle was recently repaired before this DTC was set, check that the ECU was programmed correctly and that the correct parts were installed on the vehicle.
